[0008] Preferably, the fixing element includes a first clamping member connected to the adjustment base, a second clamping member is hinged on the first clamping member or the adjustment base, a first connecting ear seat is provided on the first clamping member, and a second connecting ear seat that is interconnected with the first connecting ear seat is provided on the second clamping member, and the first connecting ear seat and the second connecting ear seat are connected by a connecting bolt.

[0009] Compared with the prior art, the present invention is characterized in that a connecting rod is hingedly connected to the connecting member, the connecting rod is hingedly arranged with the dining board, a slide is provided on the left and right sides of the dining board, the front end of the slide is connected to a locking groove extending upward, and the connecting member is provided with a limiting column that can move within the slide and the locking groove. Under the connection action of the connecting rod, the present invention allows the dining board to be flipped and folded relative to the connecting member. Under the cooperation of the slide, the locking groove and the limiting column, when the table board is unfolded for use, the limiting column slides from the slide into the locking groove, thereby achieving support locking to prevent the dining board from flipping backward and downward. When folding, the limiting column slides from the locking groove into the slide until it slides to the end of the slide, thus completing the folding. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] See also Figures 1-6A folding dining board for a walker comprises a dining board 1 and a connecting member 2 provided on the left and right sides of the dining board 1, a connecting rod 3 being hinged on the connecting member 2, and the connecting rod 3 being hinged to the dining board 1, a slide 4 being provided on the left and right sides of the dining board 1, a locking groove 5 extending upward being connected to the front end of the slide 4, and a limiting column 6 movable within the slide 4 and the locking groove 5 being provided on the connecting member 2. Under the connecting action of the connecting rod, the dining board can be flipped and folded relative to the connecting member. Under the cooperation of the slide, the locking groove and the limiting column, when the table top is unfolded for use, the limiting column slides from the slide into the locking groove, that is, support locking is achieved to prevent the dining board from flipping backward and downward. When folding, the limiting column slides from the locking groove into the slide until it slides to the end of the slide, and the folding is completed.
